This lab basically combines two different labs and makes it into one common story for creating VxLAN over MPLS.
- [Basic MPLS VPN] (https://gns3vault.com/mpls/basic-mpls-vpn/) setup is very nicely explained in the gns3vault site
- For VxLAN setup using Mininet - Firstly a great explanation by David Mahler in VXLAN overlay networks with Open vSwitch and similar lab also recreated with some useful python code for creation of mininet topology explained in Mininet VXLAN example video.
